These DEF crystal deposits block the flow of DEF and can even lead to premature failure of DEF system components. Prevent costly repairs with regular use of NuDEF. NuDEF’s triple-action formula is the world’s first DEF treatment and stabilizer designed to help fix, maintain, and prevent issues with your truck’s DEF system. Extreme weather High and low temperatures also take their toll on DEF system components. Extreme heat can accelerate the crystallization of DEF while extremely cold temperatures can cause DEF to freeze solid and potentially damage DEF system parts. NuDEF combats temperature related DEF issues by preventing DEF from evaporating quickly and lowering the freezing point of DEF. Wear and tear DEF crystal blockages and extreme weather create unnecessary wear and tear on your DEF system. DEF pumps need to work harder in order to keep the DEF flowing while lines and injectors can clog up and stop the flow of DEF completely. Regular use of NuDEF not only keeps all system components clean, it also lubricates delicate parts. For use in all diesel engines with DEF Cars & SUVs Light duty trucks Heavy duty trucks Semi-trucks RVs Heavy equipment American Owned - American Made NuDEF is dedicated to keeping American trucks and heavy equipment moving. NuDEF can help prevent the following diagnostic trouble codes (DTCs) Review: Extend the life of your DEF - I was really happy to find this product. Living in Alaska, and the DEF being a concern with its 2 year life span, it doesn’t always get all used with our short travel season. It’s not a problem if I drive the Alaska Highway to the States, but that’s not always the case. My DEF freezes in its tank over winter but that’s no problem. Being able to extend the shelf life of DEF is a no brainer. If this product works as advertised I’ll be a Happy Camper. Although I haven’t had a chance to experience its attributes yet, I will this summer. Not driving to the States this summer through Canada but will be taking a tour around all of Alaska’s 800 miles of roads to use up some DEF and give this product a workout .
